A Practical Introduction To Realtime Systems

A Practical Introduction to Realtime Systems for Undergraduate Engineering This is an introduction to realtime systems for engineering students who are not focused on computer or software engineering. This document is intended for MTE doscientos cuarenta y uno Introduction to Computer Structures and Realtime Systems.

The authors accepts no responsibility for damages, if any, suffered by any party as a result of decisions made or actions based on these course diapositivas for any other purpose than that for which it was intended. A one paragraph summary of this text is as follows: This course will being by introducing the requirements and constraints of realtime and embedded systems, together with examples. Next, we will consider various programming paradigms, appropriate characteristics for embedded and realtime programming languages, and an introduction to the C programming language and contrast it with C++. We continue by describing the organization of a computer, including descriptions of Turing machines, register machines, main memory, processor architecture and operating systems. Continuing from here, we describe static memory allocation and the call stack, and then consider dynamic memory allocation, including numerous variablesizedblock strategies, their appropriateness for realtime systems and various implementations in FreeRTOS. We also consider automatic memory allocation, including garbage collection. Following this, we discuss the idea of threads and tasks running in parallel, looking at examples of sorting in parallel, and the data structures necessary to maintain threads
